TORONTO - The union representing journalists at 35 media outlets waded into the Ontario election Monday, urging its members not to vote for the Progressive Conservatives.

Unifor Local 87-M — which represents media workers at The Globe and Mail, the Toronto Star and the Toronto Sun, but not The Canadian Press or CBC — said it has no choice but to break its traditional silence during elections.

Local president Paul Morse said the union is not telling members who to vote for, but "asking them to vote for someone other than (Tory Leader Tim) Hudak and his party."

The group took aim at what it calls Hudak's "anti-labour agenda" in a video sent to its 2,600 members.

This comes a week after a similar statement by the union representing the Ontario Provincial Police prompted the Tories to question the force's impartiality.

Unifor's unusual move was quickly condemned by high-profile federal Conservatives such as Treasury Board President Tony Clement and Employment Minister Jason Kenney, who called it a sign of media bias.

"Journalists' union picks sides in ON election (…) but we're told to believe there's no such thing as liberal media bias," Kenney wrote on Twitter.
